Allow setting environment variables to see things like default tags

[nitrocode]

Describe the Feature

It would be nice to set env vars for each run so we can take advantage of unsupported TF input vars.

e.g.

TF_AWS_DEFAULT_TAGS_<tag_name>=<tag_value>

https://github.com/hashicorp/terraform-provider-aws/releases/tag/v5.62.0

See hashicorp/terraform-provider-aws#33339

Technically this feature request could be simply to add support for specifically env var for adding tags to default tags but id prefer being able to add arbitrary env vars instead. That way atmos will always be able to support the next terraform env var feature.

Expected Behavior

Yaml env vars to control terraform behavior

Use Case

Id like to set my env vars to match the following

env:
  TF_AWS_DEFAULT_TAGS_repo: org/repo
  TF_AWS_DEFAULT_TAGS_dir: {{ atmos.component }}

Describe Ideal Solution

See above
